LED street lamp capable of monitoring PH value of acid rain

Abstract

The invention discloses an LED street lamp capable of monitoring the PH value of acid rain. The LED street lamp comprises an upper shell and a lower shell. The upper surface of the upper shell is concave downwards to form collection and sedimentation grooves, storage grooves and a guiding cone, which are arranged from outside to inside. The collection and sedimentation grooves are separated from the storage grooves by means of flooding rings. The storage grooves are separated from the guiding cone by means of collecting rings. An arc-shaped drainage plate at least covering the flooding rings is arranged above the upper shell. The gap between the arc-shaped drainage plate and the upper shell is taken as a rainwater collection inlet. The lower part of the guiding cone is connected with a PH measurement device by means of a guide pipe. A relatively reasonable rainwater collection process can be formed, a sedimentation effect on to-be-detected rainwater is achieved, damage of particle impurities in rainwater on a sensitive PH probe is avoided, that is, all that is needed is to meet a certain amount of rainfall, measurement can be conducted, and inaccurate measurement caused in the rainfall process with a small amount of rainfall is avoided.

Description

technical field [0001] The invention relates to the field of street lamps, in particular to an LED street lamp capable of monitoring the pH value of acid rain. Background technique [0002] Street lamps refer to lamps that provide lighting functions for roads. They generally refer to lamps within the road lighting range in traffic lighting. They are composed of lamps, electrical appliances, light sources, lamp poles, lamp arms, flanges, and foundation embedded parts. The stock of street lamps in China is between 28 million and 30 million. In recent years, the number of new street lamps added every year is 15%-20%, about 3-6 million. According to the number of newly added street lamps each year, all of them are LED lamps, calculated at 1000-2000 yuan each, the annual increase is 3 billion-6 billion yuan. The failure rate of LED street lights over 6000 hours is less than 1%. Lighting accounts for about 19% of the world's electricity consumption. If the efficiency of the lig...
